Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Referring to fig. 1-3, a passenger elevator safety car top guardrail comprises an air pump 1; the inflation tube 2 is communicated with the air pump 1, and the inflation tube 2 is communicated with a guardrail assembly; the guardrail component comprises a plurality of outer tubes 3, sliding tubes 4 are connected in the outer tubes 3 in a sliding mode, the outer tubes 3 are communicated with inflation tubes 2, the sliding tubes 4 are fixedly connected through steel cables 8, air bags are arranged between the sliding tubes 4, and the air bags are communicated with the sliding tubes 4.

In this embodiment, air pump 1 cooperates with gas tube 2 to supply air for the guardrail module, be used when carrying out elevator maintenance and repair operation, the normality gasbag is in the shrivelled state, and slide tube 4 then retrieves in outer tube 3, outer tube 3 and slide tube 4 are in the whole height of accomodating the state about 0.6m, the operation personnel also can relax strides across the guardrail this moment, and after aerifing, the guardrail module can reach about 1.5m after aerifing, on the one hand the guardrail module can not interfere the normal operating of elevator under the normality, and when carrying out the operation, then have sufficient height, the whole height of guardrail is higher than the health focus of most ordinary people, possess higher security, although the gasbag is flexible support, but under the circumstances of cooperation steel cable 8, make the guardrail module can block the user and drop, guarantee that it has the safeguard effect, on the other hand this kind of guardrail also satisfies lightweight demand, can not too much increase elevator operation load.

Preferably, the gasbag includes gas pole 5 and lower gas pole 6, gas pole 5 sets up through gas post 7 intercommunication with lower gas pole 6, gas pole 5's both ends and slide tube 4 fixed connection go up, gas pole 6's both ends and outer tube 3 fixed connection down, in this kind of design, because when the operation of car top, the staff adopts appearance operation more to probably fall down backward because of squating hard excessively when the operation, a lower gas pole 6 that sets up both ends and outer tube 3 fixed connection for protect the user, and gas post 7 that sets up is used for connecting gas pole 5 and lower gas pole 6 on the one hand, and on the other hand also can improve the whole safeguard effect of guardrail.

Preferably, the lower extreme fixedly connected with supporting seat 9 of outer tube 3 is a plurality of fixedly connected with connecting plate 10 between the supporting seat 9, the lower extreme and the link fixed connection of lower gas pole 6 set up connecting plate 10 and are used for connecting the bottom plate of outer tube 3, and connecting plate 10 is used for fixing on the sedan-chair top simultaneously, realizes guardrail and elevator car's fixed.

Preferably, the lower fixed surface that is close to the connecting plate 10 of elevator sedan-chair door is connected with pressure sensor, and is provided with the controller on the pressure sensor, the controller sets up with 1 intercommunication of air pump, because this kind of guardrail needs pneumatic air pump 1 to realize the safeguard effect, and some operating personnel probably lack the understanding to this kind of guardrail, so set up pressure sensor, make the operating personnel trigger pressure sensor when climbing on the sedan-chair top, realize the automatic operation of air pump 1.

Preferably, an extension plate 11 is further fixedly connected to the connecting plate 10 close to the pressure sensor, and the connecting plate 10 has a narrow width and is easy to directly walk over due to a large step of an operator, so that the extension plate 11 is arranged to enlarge the sensing area.

Preferably, one side of the air bag is provided with an exhaust hole 12, and a whistle is embedded in the exhaust hole 12, on one hand, the exhaust hole 12 is used for exhausting air in the air bag, so that the air bag is in a shriveled state after the air pump 1 stops running, and on the other hand, the whistle is used for reminding an operator, so that the operator can remember to close the air pump 1 after the operation is completed.

The above, only be the embodiment of the preferred of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, which are designed to be replaced or changed equally, all should be covered within the protection scope of the present invention.
